That’s funny, but PowerPoint stop working today without any visible reasons. Error message about service anavailable

I tryed to get into PowerPoint Service Application, but System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

and this in log:

1: “Could not find default ServiceProxy or it does not implement IWacServiceApplicationProxy”

2: “Unhandled exception caught when executing web method handler: System.NullReferenceException”

First of all – re-create PowerPoint Service Application. Problem with given key is gone.

Investigation… Something wrong with the PowerPoint application proxy. This solution using UI did’t work for me and  . It was not hooked up to the default proxy group, but admin pages said different. (Thanks to Dale Hirt)

Get-SPPowerPointServiceApplicationProxy | Remove-SPPowerPointServiceApplicationProxy -confirm

Add new one w-AddToDefaultGroup switch:

Get-SPPowerPointServiceApplication | New-SPPowerPointServiceApplicationProxy -Name “PowerPoint Proxy” -AddToDefaultGroup

Verification:

$(Get-SPPowerPointServiceApplication).ServiceApplicationProxyGroup.DefaultProxies

Sharepoint 2010 Error Opening Root Site Page

with 2 comments

We got strange error after installing SP1 for SharePoint 2010.

When opening root site page we got an error “Server error in ‘/’ application”.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:
[NullReferenceException: Object reference not set to an instance of an object.]
Microsoft.Office.Server.Administration.UserProfileApplicationProxy.get_ApplicationProperties() +134
Microsoft.Office.Server.Administration.UserProfileApplicationProxy.get_PartitionIDs() +44
Microsoft.Office.Server.Administration.UserProfileApplicationProxy.IsAvailable(SPServiceContext serviceContext) +329

Fast, and may be not correct, solution is delete User Profile Service Application and restart IIS (iisreset).

I’ll ckeck solution with re-creation this service and update this post then….

Word and PowerPoint File Open in Browser Error

with one comment

Sometimes we get an error in Office Web Application like this:

Word Web App cannot open this document for viewing because of an unexpected error. To view this document, open it in Microsoft Word.
Error Id: e526e7cf-f17a-48ee-85ee-916c593e0569, 20110415162644

What we can see in logs? Surprise!

DownloadManager: Exception thrown downloading file \\fs001\Anikin, Alexander\Agency contract.docx: System.UnauthorizedAccessException: Access to the path ‘C:\Windows\TEMP\waccache\30091891-f580-40fb-a151-9ff2114df390\DEV_ow_services\e7c940c5-2bc8-471b-b63d-37507944b53a\’ is denied.

Sharepoint Services Pool (OWA workrs under) account can’t write into the Temp\waccache folder any more.

I’be found this, but solution 1 don’t work for me. I add permissions for this folder to my accounts and it works!

I don’t know why it happens. Conversion service use this folder for temp files, but it start creating folders without needed permissions.
